Answer
A is true but R is false.
Explanation — Bayer's process is used for the purification of bauxite ore. Where, bauxite is converted into alumina. Which is reduced to aluminium using electrolytic reduction. Hence, assertion (A) is true.
Refining of aluminium is done by hoope's electrolytic process not bayer's process. Hence, reason (R) is false.
